Dunno if this will help, but here goes:
I went a couple of years ago with a girl I was fucking with (literally), never done anything like it before (sex clubs that is) so had nothing to compare with.
First time was a niche sort of night, got given a tour before the event. Dungeon downstairs (lots of bdsm stuff there) and then upstairs they have an office role play are for the secretary/boss fetishes, a room with a fuck swing and another massive room with a bed and all sorts of other equipment for people to fuck on. That night was really nice, was only a small group of couples, and the staff were really friendly and nice, no one pushed boundaries.
Then I went again to their ‘no strings’ event, that was awesome!! Only members were allowed upstairs this time, so non-members could go for naughtiness in the dungeon, which gets overcrowded as the night goes on. Was a really good vibe and atmosphere, no one with an attitude (including staff). They were very very strict on dresscode though. Had a lot of staff making sure everyone was ok as well.
